Resize PDF Pages — Change Page Dimensions (A4, Letter, Custom)

Change PDF Page Size to Any Dimension

Got a PDF designed for US Letter (8.5x11") but need to print on A4 (210x297mm)? Or need to resize a large poster PDF to fit standard paper? MyPDF's Resize Pages tool handles all page size conversions.

Common Size Conversions

A4 → Letter	International document for US printing	Letter is standard in the US
A3 → A4	Poster/spreadsheet to standard size	Fit on regular printers
Custom → A4/Letter	Odd-sized exports to standard paper	Normalize for printing
Any → Custom	Specific dimensions needed	Custom printing requirements

How to Resize Pages

Step 1: Upload Your PDF

Open the Resize Pages tool and upload your document.

Step 2: Choose Target Size

Select a preset (A4, Letter, Legal, A3, A5) or enter custom dimensions.

Step 3: Set Scaling

• Scale to fit — content shrinks or grows to fit the new page size (maintains aspect ratio)
• Center on page — content stays original size, centered on the new page
• Stretch to fill — content stretches to fill the new size (may distort)

Step 4: Download

Click "Resize" and download the resized PDF.

Tips

1. Use "Scale to fit" for most conversions — it's the safest option that preserves readability
2. Check margins — resizing may create uneven margins; adjust if needed
3. Resize before printing — don't rely on printer scaling; it often causes unexpected results
4. Batch resize — upload multiple PDFs and resize them all to the same size

Frequently Asked Questions

Does resizing affect text quality?

If the PDF contains real text (not scanned images), the text re-renders at any size with no quality loss. Scanned PDFs may lose some clarity when scaled up.

Can I resize individual pages differently?

Yes — select specific pages and apply different sizes to each if needed.

What happens to annotations and form fields?

They scale proportionally with the content.
